A 92 km (57 mile) point-to-point ultramarathon from Glasgow to Edinburgh primarily following the Forth & Clyde and Union Canal towpaths. The route is largely flat with minimal elevation gain, offering a continuous runnable surface on compacted path with occasional urban sections and bridges.

The event is typically held in early autumn when conditions are cool but variable.

A 50-mile Lake District crossing designed to be completed in a single push, using a point-to-point route that strings together big Lakeland hills and valleys. The organiser positions it as a fully supported challenge day (rather than a self-managed outing), with the key logistics, transport, support points and the day’s structure, set out in the official event information. It’s a proper Lake District day: significant climbing, long stretches between landmarks, and conditions that can change quickly, especially on higher ground.
